The outer packaging didn't apply for a patent for appearance, which was plagiarized. What should I do?

Simple steps to apply for a design patent: 1. Determine the articles applying for design patents, and conduct patent search to see if there are the same designs that want to die; 2. Draw or photograph the object and choose a clear six-sided view; 3. Modify pictures or photos with software; 4. Fill in the form as required; 5. Apply online or go to the local patent agency to apply. It takes about 6 months to 8 months for an appearance patent to be applied for and authorized.
